You are completing a bounded JavaScript coding task. Return only the requested JSON object with complete source files and brief review notes. Do not claim to have edited files, run commands, or used tools. You have no tool access. Do not include hidden reasoning.

USER
Implement the following Node.js 18+ CommonJS function from its current source. Return complete replacement source for src/slugify.js. Do not add dependencies, imports, I/O, or other files.

Required behavior:
1. slugify(value) returns an empty string for every non-string input.
2. Normalize string input to Unicode NFC, then lowercase it using JavaScript toLowerCase().
3. Preserve Unicode letters, numbers, and combining marks. Replace each consecutive run of all other characters with one ASCII hyphen.
4. Trim leading and trailing hyphens. Preserve the CommonJS export { slugify }.
5. Existing ASCII behavior must continue to work. Examples: Hello, World! -> hello-world; two   words -> two-words; null -> empty string.
6. Additional examples: Café déjà vu -> café-déjà-vu; decomposed Cafe\u0301 -> café; 中文 测试 42 -> 中文-测试-42; **hi___there** -> hi-there; only punctuation or whitespace -> empty string.

Current src/slugify.js:
```javascript
function slugify(value) {
  if (typeof value !== "string") return "";
  return value
    .trim()
    .toLowerCase()
    .replace(/[^a-z0-9]+/g, "-")
    .replace(/^-+|-+$/g, "");
}

module.exports = { slugify };


```

Return exactly one JSON object with this shape:
{"files":{"src/slugify.js":"complete JavaScript source as a JSON string"},"review_notes":["at most four brief implementation or assumption notes"]}
No Markdown wrapper. You are returning code for someone else to evaluate locally; do not say that tests passed or that you ran them.

Na de vaste controles merkten we dat Haiku zich had genormaliseerd /// naar een lege tekenreeks in plaats van /. Bij een afzonderlijke lokale controle werden twee GET-regels gebruikt, met voorvoegsels /// en /, gericht op eerste en tweede in die volgorde. Voor /wat dan ook, het contract schrijft voor dat eerste.

Haiku is terug tweede; Sonnet en Opus zijn teruggekeerd eerste. Deze extra controle vloeide voort uit de codereview en staat los van de twaalf controles die voorafgaand aan het testen zijn vastgesteld. Het heeft geen invloed op de scores daarvan.

USER
Repair a Node.js 18+ CommonJS route selector. Return complete replacement src/router.js and an additional test/router-added.test.js using node:test and node:assert/strict. Do not add dependencies or edit existing tests. Do not use I/O other than the test runner, network, child processes, timers, or any files beyond the two requested outputs.

Contract for chooseRoute(request, rules):
1. Invalid request or rules returns null, without throwing. Request must be a non-null, non-array object; method must be a nonempty ASCII-letter string; path must be a string beginning with /. Rules must be an array.
2. Before matching, remove the request path's query and fragment starting at the earliest ? or #. Do not URL-decode or collapse interior slashes.
3. Ignore invalid rules. A valid rule is a non-null, non-array object with method '*' or a nonempty ASCII-letter string, prefix a string starting with / containing neither ? nor #, and target a nonempty string.
4. Compare methods case-insensitively. Prefer any matching exact-method rule over all wildcard-method '*' rules, even if a wildcard has a longer prefix. Use wildcard rules only if no exact-method route matches the path.
5. Remove trailing slashes from a rule prefix, except that an all-slash prefix normalizes to /. A prefix matches the path only at a segment boundary: /api matches /api and /api/users, never /apix. Root / matches every valid request path.
6. Within the chosen method group, choose the longest normalized matching prefix. On equal prefix length, choose the earlier rule in the original input array. Return its target. Return null if none matches.
7. Do not mutate the request, rules array, or rule objects, including order or prefix strings. Preserve module.exports = { chooseRoute }.
8. Add tests for segment boundaries, query/fragment removal, method precedence, ties, malformed inputs and immutability. Existing simple GET /api/users and POST-no-match cases must still pass.

Current src/router.js:
```javascript
function chooseRoute(request, rules) {
  if (!request || !Array.isArray(rules)) return null;
  for (const rule of rules) {
    if (request.method === rule.method && request.path.startsWith(rule.prefix)) {
      return rule.target;
    }
  }
  return null;
}

module.exports = { chooseRoute };


```

Existing regression cases (unchanged): rules [{method:'GET',prefix:'/api',target:'api'},{method:'GET',prefix:'/api/admin',target:'admin'}]; GET /api/users returns 'api'; POST /api/users returns null.
